Loop Handle
The loop handle (R) is an adjustable rounded handle mounted on the shaft for support and control. The handle is designed to help control the machine in different positions, ideal for reaching tough spots. The handle is large enough to accommodate a gloved hand comfortably.

Quick-Release Coupling
The quick-release coupling system makes it easy to switch between Kombi attachments. In addition, this feature allows KombiSystem equipment to be dismantled into two parts for easy transport and storage and then re-assembled quickly without tools.

Split Shaft
A split shaft and special toolless quick-release coupling lets you easily switch between attachments, making the KombiSystem highly versatile as well as easy to transport and store.

Anti-Vibration System
STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Electronic Ignition ModuleThe electronic ignition provides reliable starting and because it is fully enclosed, it is protected from moisture and debris for longer service life.

Purge Pump Primer
A small fuel pump delivers fuel to the carburetor when pushed, reducing the number of starting strokes required following extended breaks in operation.

Multi-Function Control Handle
Having easy access to all of the controls on one comfortable handle help makes it easier to complete tasks so the operator’s hand never has to leave the handle.
